2teez++. Using symlink avoids messing with the unknown system default shell:

Passing unquoted variables to a single-string system really begs for trouble, as soon as variables contain meta characters. Quoting rules differ with the shell used (and become a real nightmare on Windows), and there is no safe way to find which rules work as intended.

Using symlink also avoids the overhead of creating a new, complex process for just a single kernel call, and gives a clear error code in $! instead of returning some obscure exit code and some random text on STDERR of the child process.

    [Discipulus]: how I can tell in which perl version was included List::Util 1.29 ?
    [Discipulus]: to specify use 5.0.x to be sure to have pairmap from the module..
    [Corion]: Discipulus: I think Module::Corelist ( or corelist ) can tell you that
    [Corion]: Meh - Module::CoreList
    [choroba]: Just use List::Util 1.29
    [choroba]: Be kind to people using old Perl with newer version of the module
    [Corion]: But why not simply specify 'List::Util' => 1.29 in your prerequisites? People might install a more recent version of the module into their Perl
    [Corion]: (what choroba said)
